Priolube™ EF 3446
Priolube™ EF 3446 is a low viscosity synthetic ester base oil that has been developed to meet the needs of next-generation electric vehicles. With very low traction, is especially suitable for the formulation of EV transmission and e-axle lubricants where the formulator wishes to improve efficiency. It is compatible with Group III and Group IV base oils, is highly oxidatively stable and is compatible with industry standard elastomers as well as copper.
Applications:
- Driveline and transmission lubricants for electric vehicles
